RECENT NEWS: The PMRA has released it re-evaluation of 2,4-D in August of 2006 and has stated: "2,4-D does not pose unacceptable health risks and is an effective weed-control product when used in accordance with label directions." The full document of the extensive recent evaluation on this common weed killer product can be found here.
Also please read the April 2006 results of the European Commission, United States Environmental Protection Agency, World Health Organization and Health Canada review of 2,4-D which states: "the herbicide 2,4-D does not present a health risk to homeowners (including children and pets) farmers and pesticide applicators when product directions are followed." 2,4-D Review
Again, study after study shows this product to be safe when used according to directions!

The decision to ban pesticides was then challenged by lawn care companies on the grounds that a local council does not have the authority to stop people from using a federally and provincially licenced product, which has been tested and proven safe. They argued that the pesticide industry is the most regulated, tested and licensed industry in Canada. As well, Canada has some of the strictest guidlines on use and registration of pesticide products in the world. The Supreme court of Canada ruled that, although regulated and controlled at higher levels of government, a local goverment can over rule this, and effectively null and void legislation as they see fit. This may have implications for other federal laws which may be overturned at the municipal level, including the criminal code of Canada!
The truth is some pesticides are more harmful than others, just as some products under your kitchen sink are harmful, and others are not. The extremists tactic is to group the safe products used in the lawn care industry with harmful products that we don't use, have never been used in Canada, or have not been used for decades.
LICENSED SPRAYERS ARE SAFE: There is no industry in Canada as regulated as the pesticide industry, including pharmacuticals. In Ontario a lawn care owner must have a license to operate a spraying business and a separate license to actually do the spraying. All those assisting in a spraying operation must have license or be spraying technicians.
These licenses involve studying and completing Ministry of Environment tests on the proper identification of pests, mixing and application of pesticides, and above all proper safety and disposal of products. Licenses must be renewed on a yearly basis, special insurance requirements must be met, and fines for misuse or careless use of a product are heavy.
Pesticide applicators are required to post warning signs on lawns, use the safest and least possible amount of product to create a beneficial effect, and must apply the product in the safest manner possible.
STUDIES AND MORE STUDIES: For a product to be registered for use as a pesticide in Canada it most go through an overwelming battery of tests designed to determine the safety and effectiveness of the product. Bioaccumulation, half-life, leathal dose, modes of entry, soil and water movement, carcinigicity, and many other tests are completed over a ten year period, at different independent laboratories at a cost of millions of dollars before a product can be deemed safe.
The truth is, pesticides that cause the problems extremists talk about would simple never get registered for use in Canada. In fact many of the studies linking health problems and pesticides, used by extremists, are based on products that have never been used in Canada, were not used according to proper directions, or have been banned for decades. It is unfair to compare these kinds of chemicals to those used in lawn care.
LAWN CARE PRODUCTS: In the lawn care industry, the best way to maintain a weed free lawn, is to have a thick, green healthy lawn. However, weeds can become a problem on neglected lawns, those that have suffered insect damage or physical damage (foot traffic etc.). Fortunately we have an extremely safe and effective chemical for controlling broad-leaf weeds.
The main ingredient in Killex, Par3, Trillion and many other weed control products is 2,4-D. This is the main chemical used by the lawn care industry, and it's safety is of so little issue, that extremists seldom mention it in their anti-pesticide campaigns. Instead they dwell on pesticides as a whole, or on those that never have, and never will be used in the lawn care industry. 2,4-D has been used in Canada since 1947. It has been the focus of over 4000 studies which consistently conclude the following;
There are many good sites that have studies, summaries and basic information on pesticides.
